7 Claims. 31. 184-91) This invention relates, to improvements in oil cups and similar lubricating devices and to an improved ca for closing the upper ends thereof. Electric motors and other machinery are now equipped with oil cups in the form or a short tube which is threaded or otherwise secured in a bore leading to the part to be lubricated. Such oi] cups are provided with a normally-closed, spring-operated lid which serves to exclude dust or any objectionable matter from the tube. These lids, as ordinarily constructed, have a relatively smooth lower face which cannot be conveniently engaged by an oil spout to open the lid and hold it in an open P ition while oil is being fed to the tube, and it is necessary to use both hands timing the oiling operation.

Objects of this invention are to provide an oil cup or tube of simple, economical construction having a lid which is provided on the circumferential edge thereof with depending teeth for engaging the spout of an oil can, whereby the oil can can be used with one hand to open the lid and hold it in an open position while 011 is fed from the spout to the tube.-

The above and other objects and advantages are accomplished by the novel construction, combination, and arrangement of parts illustrated and hereinafter described with reference to the particular adaptation'thereof disclosed in the drawing, it being understood that the invention is not confined to the exact form. illustrated and that changes and modifications may be mademodified form. of the invention.

In the particular adaptation of the mvention shown in the drawing, the numeral 3 is employed to denote a. tube which is provided with a reduced lower end portion 6a which may be threaded or otherwise secured in a bore leading to a hearing or other part to be lubricated. The tube 3 is provided adjacent the upper end thereof with a lug I which projects from the rear side thereof. The lug I may be of any suitable construction but as shown is provided with an upper hit wall la and side walls lb which depend therethereof presented downwardly to engage the free end of the tube 6, The main portion of the lid 8 is larger than the upper end of the tube and the marginal portion thereof projects beyond and overhangs the wall of the tube when the lid 8 is in a' closed position. The downwardly projecting marginal portion of the lid 8 is notched to provide teeth I I. In the drawing there is illustrated a-lid 8 having a continuous row of teeth I I which project downwardly from the forward and lateral sides of the lid. As shown in Figures 1 and 2, the teeth! I are inclined rearwardly but it is understood that the teeth may be of any suitable form and arranged in any suitable manner which will accomplish the purposes of the invention.

The lid 8 is provided on the rearwardly presented edge thereof with an extension 9 having depending side walls which embrace the lug l. The side walls of the lug l and the side walls of the extension 9 are provided with aligned boresin which a pin III is received to hingedly connect the cap 8 in an operative position on the tube 6. A spring 54 is mounted on the pin l0 and positioned in the cavity is with one end thereof engaging the rear edge of the extension 9 to normally hold the lid 8 in a closed position.

In Figure 4 there is shown a list lid 8b having a flange depending from the outer edge thereof. The flange-is provided with depending teeth I In which serve the same purpose as the teeth H.

In use the spout l2 of an oil can or other device is positioned under the projecting edge of the,cap 8. The spout i2 is then moved upwardly to open the lid 8 and oil is forced from the spout 42 into the tube 6. The teeth H engage the spout 2 to prevent unintentional slipping of the spout from the lid during the ailing operation.

For the most successful and convenient operation, the depending teeth should be substantially spaced from the tubular wall of the stem, so that the teeth may have reliable engagement with the oil spout andso that slipping of the oil beyond; said stein 'and a series of closely spaced depending teeth extending along substantially the entire circumferential edge of said free edge portion.

2. In an oiling device, a tubular stem, a lid hinged thereto to close the open end thereof, the

circumferential edge of said lid overhanging said' open .end, and teeth depending from said circumferential edge throughout substantially the entire free portion thereof.

3. In an oiling device, a tubular stem, a lid hinged to' one side thereof, said lid operable to close the open end of said stem, means yieldably holding said lid in a closed position, the circumferential edge of said lid projecting beyond said 7 r stem, and teeth depending from substantially the entire free portion-0f said circumferential edge in spaced relation to said stem;

4. In a lubricating tube, a tubular stem, a lid hinged thereto and projecting beyond the side walls thereof, and rearwardly inclined teeth depending from substantially the entire free circumferential edge of said lid.

5. In a lubricating tube, a tubular body, a. lid hinged thereto for movement to and from the open end thereof, a spring yieldably holding said lid in a closed position on said open end and a series of teeth projecting downwardly from the free circumferential edge of said lid for engaging an oil delivery spout, said teeth inclined in the circumferential plane of said edge, toward the hinged end of said lid.

6. In a lubricating device, a tubular stem, a lid pivotally connected to said stem to close the open end thereof, the free edge portion of said lid projecting beyond said stem, and a series of teeth depending from said free edge portion of said lid and with their inner surfaces substantially spaced radially outward from the outer wall of said tubular stem.

7. In a lubricating device comprising a tubulaistem and a lid pivotally connected to and normally closing said stemand having a projecting free edge portion, that improvement which consists in providing a series of teeth depending from said free edge portion of said lid and with their inner surfaces substantially spaced radially outward from the outer wall of said tubular stern for effective and reliable engagement by an oil spout inserted thereunder.
